5.4 OPTIWAVE 8300: Replacement of the signal converter
You can replace the signal converter of an OPTIWAVE 8300 level transmitter that has an Ex
approval that agrees with EC-Type Examination Certificate KEMA 04ATEX1218 X. But do the
checks that follow:
You must attach an adaptor when you replace the signal converter with an OPTIWAVE-M 7400
signal converter. Use the spare parts list in the OPTIWAVE-M 7400 handbook to order the
adaptor with the new signal converter.
If you replace the signal converter, the data (temperature, voltage etc.) given in these
supplementary instructions agrees with the new device configuration.
